The present invention relates particularly to dispensing caps forbottles containing carbonated liquid, such as, 'nger ale and the like.When mixing sue a liquid with a base, it is well recognized that a muchmore palatable drink results if the bottle containing the liquid is wellshaken and the liquid forcibly dischar ed in a fine stream under theimpetus of t e liberated gas.

su sequent to removing the sealing cap, and

- while the new cap is readily apphcab e and removable, it is soconstructe as to form an air tight and rigid connection with the neck ofthe bottle when in position for o eration. Upon adjusting the cap thebott e may be shaken to liberate the gas, and valve means are rovided sothat subseao quently the liquid may be dispensed as neede One embodimentof my invention is illustrated in the accompanyin embodiment beingmerely il ustrative and in u nosense restrictive. In the drawings Figure1 is a top plan view of the new cap; Figure 2 is a vertical section ontheline 2 -2 of Figure 1, the cap being shown in connection with theneck of the bottle, and Fig- Q ure 3 shows the cap as seen from beneath.

' Referring to drawings, 10 represents the mainbody of the cap, which,as may be 'readily seen from Figure 2, is cupped to produce an annularflan e 11, the margin of a5 whichis desi ed to taround the bead 12 of astandar bottle. For somewhat more than half of its circumference theflange is extended downwardly, as at 13, and bent to fit under and ipthe bead 12. Elements m 10, 11, and 12, ust described, are preferablyformed integrally of suitably heavy spring metal, and for ease ofmanipulation the extremities 14 of flange 13 may be bent out- -wardly(be 0nd their semi-circumferential slit inwardly, as at 15 (Figures 2and 3). Seated in the upper portion of cap 10 i a washer or packingelement 16 of such configuration as to secure a snug) fit. The ele- 5oment 16 is preferably of rub er, this material havin the necessaryresiliency and du- 'rability, a though an other suitable material may beused. T e mass of this washer is such that, when the cap 10 is adjustedin operative position, its lower margin will be 'municates by a duct '20with a liner and The cap according to my invention is d esigped to beapplied to a standard bottle drawings, thistles-in other words, it-is adurable accescompressed to"form an air tight packing. Asshown in Figure2,'w-as her 16 is provided with an axial bore 17 registering with arforation 18 in ca 10. The bore 17 is enargedas at 19 an thisenlargement comspout 2lri idly secured in an aperture in the cap. Theinner cross section-pf element 21, or at least o'fits orifice, is verysmall so as to deliver an extremely fine stream. The inner portion ofelement 21 servesto hold washer 16 in proper position and to prevent theblocking of the duct upon compression of the washer. 4

A valve disc '22, mounted on a stem 23 which extends upwardly throughbore -17 and perforation 18, serves to cover enlargement 19. Stem 23 hasa button 24 mountedon its outer extremit and interposed between thebutton an cap 10 is a return spring 25. V

It will be seen that under normal conditions disc 22 will prevent theescape of any gas through duct 20 while upon depression of button 24,duct 20 will be opened, and upon inversion of the bottle, the contained1i uid will be forcibly dischar ed.

t is to be emphasized that t e cap according to my lnvention is adatable for repeated application to standar beverage botsory. I also callattention to the fact that the attachment means are substantiallypositive; that is to say, pure friction is not relied upon, but apositive gripping action is present. It will also be noted that thepressure within the bottle will tend to seat th valve disc themoresecurely.

While I have necessarily described my invention in some detail, it willbe recognized as that'various changes within the range of mechanicalskill w1ll sug est themselves to those skilled in the art. t is to beunderstood, however, that I do not limit myself except as in accordancewith the following claim.

I claim: A cap for cha'rged-bevera bottles of the type having a topperipherzfl, bead, said cap comprising depen ing opposed gripping means,said gripping means being engageable under opposite portions of saidhead upon forcedmovement of said cap substantially parallel to the bead,whereby said cap is retamable inoperative relation to said bot- '110
